Zoning fixes are absolutely required, but Texas (particularly Huston) is not a good model. While many places in Texas don't have so-called 'zoning' they manage to implement pretty much all the restrictions zoning reform advocates want fixed through things like land use restrictions on deeds (which are even tougher to reform than zoning)

Japan is the model I'd like to see: inclusionary zoning. A small number of zones that allow for maximum use.
